2.3 LED indicators

The DK6 board LED locations are shown in Figure 3. A description of each on-board LED indicator is shown in the next table.

Table 2. LED indicator functions

2.4 ARDUINO connectors

ARDUINO compatible connectors are based on Arduino R3. References on the DK6 board are CN1, CN2, CN3, CN4. The Generic expansion board OM15082 can be plugged into these connectors.

2.5 Buttons

2.5.1 Reset button

This button (SW4) is used to reset the JN5189 (note that the Link2 is NOT reset by this button).

2.5.2 ISP button

This button connects the JN5189_PIO5 (ISP_Entry) pin to ground. This should be used to set the JN5189 in ISP mode to program a binary file into the chip memory. To force entry into this ISP mode, hold down the ISP button (SW2), press and release the Reset button (SW4), then release the ISP button (SW2). This is done automatically when using the DK6 Production Flash programmer with J2 (FTDI USB interface).

2.6 User Interface button

This button (BP1) is connected to JN5189_PIO_1 and should be used as an input.

2.7 JN5189 Serial port

The JN5189 UART0 can also be connected through a virtual communication port (VCOM) UART bridge Link2 function either to a host computer connected to the J2 USB FTDI or to J15 USB Link2. By default, the DK 6 is configured to use the FTDI USB. For Link2 USB: The factory default CMSIS-DAP Link2 image includes UART bridge functionality (VCOM support), and this firmware is also available with the LPCScrypt utility, available at https://www.nxp.com/design/microcontrollers-developer-resources/lpc-microcontroller-utilities:LPC-UTILITIES power connections and measurements. For the USB FTDI, the PC driver is available on FTDI website (the FTDI chip is already configured before the carrier board release).

2.8 Board power connections

A block diagram of the board power tree is shown in Figure 5. When the JN5189 Target is to be debugged from the on-board Link2 probe, the USB mini B-type connector (J15) must be connected to a Host computer. When the JN5189 Target is to be debugged from an external debug probe, instead of the on-board debug probe, the Link USB connector (J15) must be disconnected.

Figure 5. Board power diagram: This diagram illustrates the power distribution pathways for the DK6 board, showing various power sources (USB, batteries, external supply) and their connections to different components via regulators and jumpers.

2.9 Debug Configurations

The DK6 board has a built-in debug probe referred to as "Link2". The JN5189 target wireless MCU can be debugged by the Link2 debugging probe, or from an external debug probe installed at P1. On-board jumpers JP1 and JP2 must be correctly positioned for each mode. The on-board Link2 debug probe is capable of debugging target MCU's with a VDDIO range of 1.6V to 3.6V. Check the sections below for the appropriate jumper settings and how to properly power the board.

2.9.1 Debug using on-board debug probe

To use the on-board Link debug probe:

• The jumper JP2 must be fitted in position pin 1 - 2 (Local Target).
• Jumper JP1 must be open or fitted in position 2 – 3 to enable the target JN5189.
• Connecting the mini USB J15 to a host computer will power the Link and, according to JP3, JP5 position, the JN5189 sections of the board and provide the USB link to the debug tool software.

2.9.2 Debug using external debug probe

To use an external debug probe:

• Connect the probe to the SWD (P1) connector.
• Power the JN5189 Target section of the board from the FTDI header (J1) or the Jack connector (J4).
• Fit a jumper to JP2 across pin 1 - 2 (Local Target).
• Jumper JP1 must be open or fitted across pin 2 – 3 to enable the target JN5189.
• The on-board Link2 debug probe must be unpowered, by leaving USB mini (J15) unconnected.

2.9.3 On-Board Link2 flash programming

To program the Link2 Flash, the Link2 MCU must be in DFU mode. If the Link2 already has a valid image in the flash, you will need to force it into DFU mode by placing a jumper shunt on JP5 across pin 1 - 2, then power the board by connecting the mini USB J15 to a host computer. Link2 MCU programming is performed using the LPCScrypt utility (see https://www.nxp.com/design/microcontrollers-developer-resources/lpc-microcontroller-utilities:LPC-UTILITIES). Instructions for using the tool are located at the same web page.

2.9.4 Using the DK6 to debug an off-board target

The DK6 board's Link2 debug probe may be used to debug an off-board target MCU. The on-board Link2 debug probe is capable of debugging target MCU's with a VDDIO range of 1.6V to 3.6V. To keep the on-board target JN5189 MCU from interfering with the SWD interface:

• JP1 must be fitted across pin 1 - 2.
• The Link2 debug probe SWD is connected by a ribbon cable between the P1 connector to the off-board target MCU SWD interface.
• Power the DK6 board from the Link USB connector J15.
• Fit jumper JP2 across pins 2 - 3 (External Target).

Chapter 3 JN5189 Modules

The JN5189 Module board is the JN5189 minimum system board. The module should be mounted to a carrier board as the target. There is an RF connector on this board, which can be used for RF signal testing.

Chapter 6 JN5189 USB Dongle

The OM15080-JN5189 can be used as a node in a Zigbee network as a Zigbee Control Bridge, Zigbee Coordinator, or packet sniffer. It can also be used in a Thread wireless network, typically as a dongle for Border Router, Network/Radio Co-Processor (NCP/RCP).

Figure 9. JN5189 USB Dongle: This image shows the JN5189 USB Dongle, a compact USB device designed for Zigbee and Thread networking.

Chapter 7 JN5189 current measurement

The JN5189 current can be measured:

1. Using the on-board current measurement circuit with MCUXpresso.
2. Measuring the voltage across a sense resistor (R51) in series with the supply.
3. Using a current meter on a modified DK6 board or a stand-alone module.

Each of these methods will be described in subsections below. When a board is attached, attempting to measure the lowest possible power requires the JN5189 IO pins to be configured by software to avoid any extra current from the JN5189 IO ports that have external pull-up or pull-down resistors enabled. JP6 should be opened to avoid leakage to the Link2 via the I2C and SPI connections between it and the JN5189.

7.1 Current measurement with MCUXpresso

The DK6 board has an on-board current measurement circuit consisting of a MAX9634T (IC21) current monitor chip and a 12-bit ADC (ADC122S021, IC19) with a 12-bit sample at 50k to 200ksps. The on-board MAX9634T current monitor measures the voltage across the JN5189 VBAT Vsense resistor of 3.3Ω. The MAX9634 multiplies the sense voltage by 25 to provide a voltage range suitable for the ADC to measure. The current measurement circuit is controlled by the debug processor and is not user programmable. Power measurement utilities to use this feature are available in the MCUXpresso IDE installation. Due to input offset voltage variations in the MAX9634, the current measurement circuit is not recommended for measuring current below 150uA.

7.2 Vsense resistor measurement

The voltage across a series 3.3Ω resistor with the target JN5189 VBAT can be manually measured at J14 on the PCB. The voltmeter positive probe is applied to J14 pin 1 (square pad) and the negative probe to J14 pin 2. Use Ohm's law to calculate the current (JN5189 current = measured voltage / 3.3Ω). For example, if the measured voltage is 10mV, then 10e-3 / 3.3 = 3.03mA. Note that the input current to the MAX9634 used in the on-board current measurement will be included in the voltage measured across this resistor.

7.3 Current measurement with a multimeter

Figure 10 shows the circuit for the power supply to the module. The signal VBAT is used to power the JN5189 module.

Figure 10. Power Sensing Circuit: This schematic illustrates the power sensing circuit, including the VBAT connection, a sense resistor (R51), and the power LED (DS1).

This signal goes to the module (JM1.17) and the expansion connector (J3.31).

Figure 11. VBAT Connections: This diagram shows the module connections (JM1, JM2) and the expansion header (J3) pinouts related to VBAT and other signals.

To measure the current using a multimeter, remove R51 and place the multimeter across J14 pins 1 and 2.

Figure 12. R51 Location: This image highlights the location of resistor R51 on the PCB, which is part of the current sensing circuit.

The multimeter will also measure the current taken by the VSENSE line. This signal is used to measure the voltage drop across the 3R3 resistor so that the current consumption results can be shown with MCUXpresso. The current taken from this signal is negligible but can be removed by cutting JS6.

Figure 13. Voltage Sense Circuit: This schematic shows the voltage sense circuit, featuring the MAX9634 current monitor (IC21) and the ADC (IC19).

7.4 IO Considerations

If an expansion board is not fitted, then the following IO lines are connected on the DK6 board. Setting IOs incorrectly in the software will cause current to be consumed, and this should be taken into consideration when measuring current. The following IOs are connected.

Table 3. Connected IOs

For sleep current measurements, the following additional changes are required to achieve the datasheet value; otherwise, the result is typically 600nA high.

Table 4. Additional changes

7.5 Running the DK6 board at different voltages

In order to run the DK6 at different voltages, it is necessary to disconnect the FTDI 3V3OUT signal; otherwise, this will continue to supply 3.3V to the board. The circuit is shown below in Figure 14.

Figure 14. FTDI Interface: This schematic shows the FTDI interface circuit, including the FT230XS chip and its connections for UART and USB.

It is important to leave C49 connected to Pin10 of the FT230A. To achieve this, modify the boards as shown in Figure 15.

Figure 15. 3V3OUT modification: This image shows a modification on the board to disconnect the 3V3OUT signal from the FTDI chip, illustrating the placement of C49 and the FTDI FT230X chip.
